Why is that? I wanted to do the same thing. Change the date on a MAD-GUA flight booked using miles from the 9k promotion that I have to a week earlier. Is it because it redeposits and then pulls again? Hoping not if it is same routing just date change (I know the original poster wants to change destination so that's slightly different).
